A Labor Shortage for U.S. Nuclear Plants [07Jul11] - 0 views

  • It took Japan’s Fukushima disaster to make nuclear energy interesting to students in Karl Craddock’s advanced placement chemistry class at William Fremd High School in Palatine, Ill. Too bad the buzz was about radiation plumes, iodine pills, and potential deadly threats at nuclear power plants that generate more than half the electricity in Illinois. It wasn’t the sort of talk to get kids excited about a career in nuclear energy. “It doesn’t have the cool factor right now, that’s for sure,” says Craddock, who has taught science at the suburban Chicago high school for seven years.
  • Nuclear utilities in the U.S. will need to hire nearly 25,000 people to replace the 39 percent of its workforce that will be eligible for retirement by 2016, says Carol L. Berrigan, senior director for industry infrastructure for the Nuclear Energy Institute, a Washington-based trade group. Meanwhile, U.S. universities awarded a total of 715 graduate and undergraduate degrees in Nuclear engineering in 2009, the most recent year for which data is available.
  • After nuclear plant disasters at Three Mile Island in Pennsylvania and Chernobyl in Ukraine, nuclear power lost political support in the U.S. Hiring slowed through the 1990s and nuclear workers under the age of 40 became a rarity as talk turned from expansion to shutting down existing plants. “That’s not an exciting prospect for a young person thinking about their career,” says K.L. “Lee” Peddicord, a professor of nuclear engineering and director of the nuclear Power Institute at Texas A&M University.

  • With nuclear power out of favor, the number of academic institutions offering degrees shrank to 32 in 2010 from 77 in 1975, according to the Oak Ridge Institute for Science and Education. Bachelor’s degrees awarded in nuclear engineering fell to 120 in 2001, from 863 in 1978. Power companies and engineering schools redoubled their recruiting efforts in recent years to replace retiring baby boomers and staff the 34 new plants that were on the drawing boards as of 2009. Urged by two utilities with nuclear ambitions in Texas—South Texas Project and Exelon (EXC) —Texas A&M University in College Station launched the nuclear Power Institute in 2008 to spearhead a statewide effort to train 2,000 nuclear workers, boost math and science programs at high schools, and develop a new two-year nuclear training degree with community colleges based near eight proposed new plants.
  • The Nuclear Power Institute has graduated its first two classes of technicians, yet Peddicord worries that the weak economy and the growing uncertainty overhanging a U.S. Nuclear expansion will depress interest in the program. The partners in two new reactors planned for nearby Bay City— NRG Energy (NRG) and Tokyo Electric Power, operator of the crippled Fukushima Dai-Ichi power plant—yanked funding for the project after the disaster. “The real test will come in the fall, when we look at enrollment,” he says.
  • The bottom line: Nuclear plants in the U.S. need to recruit some 25,000 new workers by 2016. Japan’s Nuclear crisis has made reaching that goal harder.

The Pro-Nuclear Community goes Grassroots [12Oct11] - 0 views

  • In recent weeks I have been excited to witness several genuine grassroots efforts in support of nuclear energy emerging on the scene. Several have already been covered on this forum, like the Rally for Vermont Yankee and the Webinar collaboration by the nuclear Regulatory Commission and the American nuclear Society. Both of these efforts proved to be very successful in bringing together nuclear supporters and gaining attention from the mainstream media.
  • I’d like to share some information about another opportunity to actively show your support for nuclear. The White House recently launched a petition program called “We the People.” Here is the description of how it works: This tool provides you with a new way to petition the Obama administration to take action on a range of important issues facing our country. If a petition gets enough support, White House staff will review it, ensure it’s sent to the appropriate policy experts, and issue an official response. One of the first and most popular petitions on the website is a call to end subsidies and loan guarantees for nuclear energy by 2013. As I write this, it is only about a thousand signatures away from reaching the White House. In response to this petition, Ray Wallman, a young nuclear supporter and filmmaker, wrote a counter petition called “Educate the Public Regarding nuclear Power.” It needs 4,500 more signatures before October 23 in order to get a formal response, and reads as follows:
  • Due to the manufactured controversy that is the nuclear reactor meltdown in Fukushima, Japan, perpetuated by a scientifically illiterate news media, the public is unnecessarily hostile to nuclear power as an energy source. To date nobody has died from the accident and Fukushima, and nuclear power has the lowest per Terra-watt hour death toll of any energy source known to man: http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html The Obama administration should take better strides to educate the public regarding this important energy source.

  • In addition to the petition for education, Gary Kahanak, of Arkansas Home Energy Consultants, released another one in support of restarting the Integral Fast Reactor program. This petition was inspired by an open letter to the White House with the same goal, written by Steve Kirsch, of the Science Council for Global Initiatives. The petition states:
  • Without delay, the U.S. should build a commercial-scale demonstration reactor and adjacent recycling center. General Electric’s PRISM reactor, developed by a consortium of major American companies in partnership with the Argonne National Laboratory, is ready to build now. It is designed to consume existing nuclear waste as fuel, be passively safe and proliferation-resistant. It can provide clean, emissions-free power to counter climate change, and will create jobs as we manufacture and export a superior technology. Abundant homegrown nuclear power will also enhance our nation’s energy security. Our country dedicated some of its finest scientific and engineering talent to this program, with spectacular success. Let’s finish the job we started. It will benefit our nation, and the world.
  • This brings me to my second reason for supporting these petitions: They represent a genuine change in approach for supporting nuclear energy. Throughout the history of commercial nuclear power generation, most of the decisions and support have come directly from government and corporate entities. This has resulted in a great deal of public mistrust and even distain for nuclear technologies. A grassroots approach may not translate directly into research dollars or policy change, but it has to the potential to win hearts and minds, which is also extremely important.
  • There has been some debate among my colleagues about the value of this approach. Some were concerned about the specific language or content of the petitions, while others did not feel comfortable signing something in support of a particular reactor that is not their preferred technology. Others have voiced that even if we get 5,000 signatures, the White House response will not have any impact on policy. While I understand and respect those points, I want to share why I decided to sign both petitions and to write about them here.
  • Those of us in the nuclear communications community ask ourselves constantly, “How do we inspire people to get involved and speak out in support of nuclear?” I see these petitions as a sign of success on the part of the nuclear community—we are reaching out and inspiring action from the ground up. nuclear supporters who are not directly employed by the industry created both of these petitions. In my mind, that is a really wonderful thing. Members of the public are taking independent action to support the technology they believe in.
  • The release of these petitions was just in time to beat an increased threshold for minimum signatures, from 5,000 to 25,000. That means that if half of ANS members take the time to sign these petitions, we will get a formal response from the White House about their plans for increasing public education on nuclear energy, and moving forward with an important Generation IV technology.
  • And finally, there is power in symbolic action

It's 2050: Do you know where your nuclear waste is? [09Sep11] - 1 views

  • Though nuclear power produces electricity with little in the way of carbon dioxide emissions, it, like other energy sources, is not without its own set of waste products. And in the case of nuclear power, most of these wastes are radioactive.1 Some very low level nuclear wastes can be stored and then disposed of in landfill-type settings. Other nuclear waste must remain sequestered for a few hundred years in specially engineered subsurface facilities; this is the case with low level waste, which is composed of low concentrations of long-lived radionuclides and higher concentrations of short-lived ones. Intermediate and high-level waste both require disposal hundreds of meters under the Earth’s surface, where they must remain out of harm’s way for thousands to hundreds of thousands of years (IAEA, 2009). Intermediate level wastes are not heat-emitting, but contain high concentrations of long-lived radionuclides. High-level wastes, including spent nuclear fuel and wastes from the reprocessing of spent fuel, are both heat-emitting and highly radioactive.
  • When it comes to the severity of an accident at a nuclear facility, there may be little difference between those that occur at the front end of the nuclear power production and those at the back end: An accident involving spent nuclear fuel can pose a threat as disastrous as that posed by reactor core meltdowns. In particular, if spent fuel pools are damaged or are not actively cooled, a major crisis could be in sight, especially if the pools are packed with recently discharged spent fuel.
  • Elements of success
  • ...17 more annotations...
  • All countries with well-established nuclear programs have found themselves requiring spent fuel storage in addition to spent fuel pools at reactors. Some, like the US, use dry storage designs, such as individual casks or storage vaults that are located at reactor sites; other countries, Germany for one, use away-from-reactor facilities. Sweden has a large underground pool located at a centralized facility, CLAB, to which different reactors send their spent fuel a year after discharge, so spent fuel does not build up at reactor sites. Dry storage tends to be cheaper and can be more secure than wet storage because active circulation of water is not required. At the same time, because dry storage uses passive air cooling, not the active cooling that is available in a pool to keep the fuel cool, these systems can only accept spent fuel a number of years after discharge.6
  • The United States had been working toward developing a high-level waste repository at Yucca Mountain, Nevada; this fell through in 2010, when the Obama administration decided to reverse this decision, citing political “stalemate” and lack of public consensus about the site. Instead, the Obama administration instituted the Blue Ribbon Commission on America’s Nuclear Future to rethink the management of the back end of the Nuclear fuel cycle.8 The US can flaunt one success, though. The Waste Isolation Pilot Project (WIPP), located near Carlsbad in southern New Mexico, is actually the only operating deep geologic repository for intermediate level Nuclear waste, receiving waste since 1998. In the case of WIPP, it only accepts transuranic wastes from the Nuclear weapons complex. The site is regulated solely by the Environmental Protection Agency, and the state of New Mexico has partial oversight of WIPP through its permitting authority established by the Resource Conservation and Recovery Act. The city of Carlsbad is supportive of the site and it appears to be tolerated by the rest of the state.9
  • France has had more success after failing in its first siting attempt in 1990, when a granite site that had been selected drew large protests and the government opted to rethink its approach to nuclear waste disposal entirely. In 2006, the government announced that it needed a geologic repository for high-level waste, identified at least one suitable area, and passed laws requiring a license application to be submitted by 2015 and the site to begin receiving high-level waste by 2025.
  • Canada recently rethought the siting process for nuclear waste disposal and began a consensus-based participatory process. The Canadian nuclear Waste Management Organization was established in 2002, after previous attempts to site a repository failed. The siting process began with three years’ worth of conversations with the public on the best method to manage spent fuel. The organization is now beginning to solicit volunteer communities to consider a repository, though much of the process remains to be decided, including the amount and type of compensation given to the participating communities.
  • the most difficult part of the back end of the fuel cycle is siting the required facilities, especially those associated with spent fuel management and disposal. Siting is not solely a technical problem—it is as much a political and societal issue. And to be successful, it is important to get the technical and the societal and political aspects right.
  • After weathering the Fukushima accident, and given the current constraints on carbon dioxide emissions and potential for growth of nuclear power, redefinition of a successful nuclear power program is now required: It is no longer simply the safe production of electricity but also the safe, secure, and sustainable lifecycle of nuclear power, from the mining of uranium ores to the disposal of spent nuclear fuel. If this cannot be achieved and is not thought out from the beginning, then the public in many countries will reject nuclear as an energy choice.
  • Certain elements—including an institution to site, manage, and operate waste facilities—need to be in place to have a successful waste management program. In some countries, this agency is entirely a government entity, such as the Korea Radioactive Waste Management Organization. In other countries, the agency is a corporation established by the nuclear industry, such as SKB in Sweden or Posiva Oy in Finland. Another option would be a public– private agency, such as Spain’s National Company for Radioactive Waste or Switzerland’s National Cooperative for the Disposal of Radioactive Waste.
  • Funding is one of the most central needs for such an institution to carry out research and development programs; the money would cover siting costs, including compensation packages and resources for local communities to conduct their own analyses of spent fuel and waste transportation, storage, repository construction, operations, security and safeguards, and future liabilities. Funds can be collected in a number of ways, such as putting a levy on electricity charges (as is done in the US) or charging based on the activity or volume of waste (Hearsey et al., 1999). Funds must also be managed—either by a waste management organization or another industry or government agency—in a way that ensures steady and ready access to funds over time. This continued reliable access is necessary for planning into the future for repository operations.
  • the siting process must be established. This should include decisions on whether to allow a community to veto a site and how long that veto remains operational; the number of sites to be examined in depth prior to site selection and the number of sites that might be required; technical criteria to begin selecting potential sites; non-technical considerations, such as proximity to water resources, population centers, environmentally protected areas, and access to public transportation; the form and amount of compensation to be offered; how the public is invited to participate in the site selection process; and how government at the federal level will be involved.
  • The above are all considerations in the siting process, but the larger process—how to begin to select sites, whether to seek only volunteers, and so on—must also be determined ahead of time. A short list of technical criteria must be integrated into a process that establishes public consent to go forward, followed by many detailed studies of the site—first on the surface, then at depth. There are distinct advantages to characterizing more than one site in detail, as both Sweden and Finland have done. Multiple sites allow the “best” one to be selected, increasing public approval and comfort with the process.
  • he site needs to be evaluated against a set of standards established by a government agency in the country. This agency typically is the environmental agency or the nuclear regulatory agency. The type of standards will constrain the method by which a site will be evaluated with regard to its future performance. A number of countries use a combination of methods to evaluate their sites, some acknowledging that the ability to predict processes and events that will occur in a repository decrease rapidly with each year far into the future, so that beyond a few thousand years, little can be said with any accuracy. These countries use what is termed a “safety case,” which includes multiple lines of evidence to assure safe repository performance into the future.
  • Moving forward
  • France, Canada, and Germany also have experienced a number of iterations of repository siting, some with more success than others. In the 1970s, Germany selected the Gorleben site for its repository; however, in the late 1990s, with the election of a Red–Green coalition government (the Greens had long opposed Gorleben), a rethinking of repository siting was decreed, and the government established the AkEnd group to re-evaluate the siting process. Their report outlined a detailed siting process starting from scratch, but to date too much political disagreement exists to proceed further.
  • Notes
  • Nuclear wastes are classified in various ways, depending on the country or organization doing the classification. The International Atomic Energy Agency (IAEA) notes six general categories of waste produced by civil Nuclear power reactors: exempt waste, very short-lived waste, and very low level waste can be stored and then disposed of in landfill-type settings; low level waste, intermediate level waste, and high-level waste require more complex facilities for disposal.
  • Sweden is currently the country closest to realizing a final solution for spent fuel, after having submitted a license application for construction of a geologic repository in March 2011. It plans to open a high-level waste repository sometime after 2025, as do Finland and France.
  • Some countries, such as Sweden, Finland, Canada, and, until recently, the US, plan to dispose of their spent fuel directly in a geologic repository. A few others, such as France, Japan, Russia, and the UK have an interim step. They reprocess their spent fuel, extract the small amount of plutonium produced during irradiation, and use it in new mixed oxide (MOX) fuel. Then they plan to dispose of the high-level wastes from reprocessing in a repository.

DOE on Nuclear Waste Site Failed Safety Culture [19Jul11] - 0 views

  • DEPARTMENT OF ENERGY DOE Response to Recommendation 2011-1 of the Defense Nuclear Facilities Safety Board, Safety Culture at the Waste Treatment and Immobilization Plant AGENCY: Department of Energy. ACTION: Notice.
  • SUMMARY: On June 09, 2011, the Defense Nuclear Facilities Safety Board affirmed their Recommendation 2011-1, concerning Safety Culture at the Waste Treatment and Immobilization Plant, to the Department of Energy. In accordance with section 315(b) of the Atomic Energy Act of 1954, as amended, 42 U.S.C. 2286d(b), The following represents the Secretary of Energy's response to the recommendation.
  • As the Board notes in the introduction to this Recommendation, DOE committed itself to establishing and maintaining a strong nuclear safety culture almost 20 years ago through Secretary of Energy Notice SEN-35-91, nuclear Safety Policy. This commitment was reiterated and confirmed in February 2011, in DOE Policy 420.1, Department of Energy nuclear Safety Policy. We agree with the Board's position that establishment of a strict safety culture must be a fundamental principle throughout the DOE complex, and we are in unqualified agreement with the Board that the WTP mission is essential to protect the health and safety of the public, our workers, and the environment from radioactive wastes in aging storage tanks at Hanford.
  • ...17 more annotations...
  • DOE views nuclear safety and assuring a robust safety culture as essential to the success of the Waste Treatment and Immobilization Plant (WTP) and all of our projects across the DOE complex.
  • Over the past year, the Department has undertaken a broad range of steps to assure a strong and questioning safety culture at WTP and sites across the DOE complex. We will only be successful if we remain committed to continuous improvement and teamwork. DOE takes all safety concerns--whether from our employees, our contractors, the Board, or third-parties--very seriously. This input is an integral part of the Department's efforts to constantly strengthen nuclear safety at our facilities.
  • Even though the Department cannot accept the allegations without the opportunity to evaluate the Board's full investigative record, in the spirit of continual improvement DOE accepts the Board's recommendations to assert federal control to direct, track, and validate corrective actions to strengthen the safety culture at WTP; conduct an extent of condition review to assess safety culture issues beyond the WTP project; and support the ongoing Department of Labor (DOL) review of Dr. Tamosaitis' case.
  • In October 2010, HSS completed its investigation, which included interviews with more than 250 employees. While HSS found that the fundamentals of a robust safety culture were present at WTP, the report identified the need for improvement in key areas, including, among others: more clearly defining federal roles and responsibilities; identifying mechanisms to strengthen trust among the workforce and better communicate information to employees; and putting in place processes to ensure nuclear safety programs remain robust and effective during project changes.
  • The corrective actions that address the recommendations from the HSS report will be fully implemented by September 30, 2011. HSS will then conduct a follow-on visit to assure that these steps were executed effectively across the project, as well as to perform additional analysis to determine if cost and schedule pressures are challenging the implementation of a robust nuclear safety culture.
  • DOE and Bechtel National, Incorporated (BNI)--the prime contractor on the WTP project--have been engaged in a variety of initiatives to strengthen the nuclear safety culture at WTP for over a year. Steps that have already occurred include completing a revision to the WTP Project Execution Plan, currently under review, to more clearly delineate federal roles and organizational responsibilities at WTP and the Office of River Protection (ORP), and conducting a number of employee forums to ensure that employees clearly understand the changes in those roles and responsibilities.
  • Also in response to the HSS recommendations, BNI commissioned a confidential survey of more than 300 WTP employees to assess if a Nuclear Safety Quality Culture (NSQC) gap existed at the site and to identify additional areas for improvement. As a result, the contractor assigned a retired Navy Admiral and former Nuclear utility executive experienced in application of Institute of Nuclear Power Operations (INPO) methods as the Manager of NSQC Implementation for the project. To date, approximately 1,600 people at the site, including all senior managers, have received training focused on making the workforce comfortable with raising issues and systematically moving issues through to resolution. In addition, over the last 13 months, BNI has conducted three all-hands meetings with DOE project team participation to emphasize the importance of a robust Nuclear safety culture.
  • Even while some initiatives are already underway, we recognize the need to continue improving nuclear safety at WTP and across the complex. To that end, DOE has developed a comprehensive action plan to address the Board's specific recommendations to strengthen the safety culture at WTP. Initial steps are discussed below:
  • The Deputy Secretary and I will continue to be personally engaged in asserting federal control to ensure the specific corrective actions to strengthen safety culture within the WTP project in both contractor and federal workforces--consistent with DOE Policy 420.1--are tracked and validated. Federal control within the WTP project has been and will continue to be asserted and regularly reinforced through our direct involvement.
  • This will include a series of ``town-hall'' style meetings hosted by senior DOE officials to highlight for workers the importance of maintaining a strong nuclear safety culture at each of our sites and to solicit their input. These forums across the DOE complex will also help improve the direct communication of safety issues between senior managers and employees. To address the concern regarding extent of condition, HSS will independently review the safety culture across the entire complex. This review will provide insights into the health of safety culture within Headquarters organizations, different program offices, and different field sites.
  • In addition, DOE and BNI are arranging Safety Conscious Work Environment (SCWE) training for BNI and ORP managers and supervisors with a firm that conducts SCWE training for the Institute of Nuclear Power Operations Senior Nuclear Plant Manager's course. We will also be joining with BNI to sponsor an independent, executive-level
  • assessment of the project's nuclear safety culture by a group of nuclear industry subject matter experts, who have experience in INPO evaluations and/or nuclear Regulatory Commission (NRC) inspections. At both a site and corporate level, we are also taking steps to enhance reporting mechanisms for safety-related concerns. At the Hanford site, we have combined the Employee Concerns Programs for ORP and the Richland Operations Office to leverage existing resources to both strengthen this important program and increase its visibility at the site.
  • Within EM Headquarters, we have established ombudsmen to act as advocates for employees and their concerns.
  • We have made it easier for employees to use a variety of avenues to raise concerns, including: the line management for each project, site employee concerns programs, union representatives, EM's Office of Safety and Security Programs, HSS, and DOE's Chief of Nuclear Safety. Each office now offers employees access to both a hotline number and general email inbox, so that workers will have the opportunity to ask questions or voice concerns either directly or anonymously.
  • We will also require that both EM Headquarters and field sites assess nuclear safety culture and the implementation of a safety conscious work environment in their annual submittals for Integrated Safety Management System (ISMS) declarations. The specific criteria will build on the existing requirements for the ISMS declarations and will be expanded to include safety culture principles not only from DOE, but also from INPO and NRC.
  • DOE does not agree with all of the findings included in the Board's report. Specifically, the conclusions drawn by the Board about the overall quality of the safety culture at WTP differ significantly from the HSS findings and are not consistent with the safety culture data and field performance experience at WTP. We are concerned that your letter includes the October 2010 HSS review in the list of ``other examples of a failed safety culture.''
  • The Department disagrees with this categorization and believes the HSS report provided an accurate representation of the nuclear safety culture-- and existing gaps--at the WTP.

What You Missed at the 55th General Conference of International Atomic Energy Agency [30Sep11] - 0 views

  • A week ago, a busy 55th General Conference closed at the IAEA, where major issues in nuclear science, nuclear safety and nuclear power were discussed, and successful projects undertaken throughout the year were highlighted. Keynote Address This year's Scientific Forum focused on water and the efforts being made by the IAEA and its partners to improve its availability and management. In his keynote address to the Scientific Forum, U.S. Secretary for Energy and Nobel Laureate Steven Chu described how nuclear techniques have proven to be powerful tools that successfully and efficiently help to find, measure, monitor, characterize and manage aquifer and ground water. "nuclear technologies and techniques can - and must - play an important role in solving the global water challenge. Isotope hydrology can provide critical information about water resources, so we can better manage them", he said. He also described how isotopic analysis can be used to verify the anthropogenic causes of climate change. In closing, Secretary Chu called for "a sustained commitment to scientific research and development to address the great challenges of our time" since support from governments is critical to unleashing innovation".
  • Nuclear Safety Nuclear safety has been on a global concern since the devastating Nuclear accident in Japan in March. The IAEA Member States developed a Nuclear Safety Action Plan that the Board of Governors approved and the General Conference endorsed. A new system which makes it easier for Member States and the Agency to exchange emergency information was launched. Following the first meeting of the Nuclear Industry Cooperation Forum, its Chair, Garry Young, who is also the Director of Nuclear Business Development at the US Nuclear power operator, Entergy, talked to Sasha Henriques from the IAEA Division of Public Information, about how important it is for Nuclear power plant operators from around the world to work together to avoid another major Nuclear accident like Fukushima Daiichi. Listen to the interview here:
  • Senegal signed the Convention on Supplementary Compensation for Nuclear Damage during the General Conference. Among other things, the Convention establishes an international fund to increase the amount available to compensate victims of Nuclear accidents. Mauritania deposited the instruments of accession to three international safety Conventions on 19 September 2011: the Convention on Early Notification of a Nuclear Accident; the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency and the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

Federation of American Scientists :U.S. Leadership Essential for International Nuclear Energy Programs [09Sep11] - 0 views

  • Global growth in the civilian nuclear energy sector represents an annual trade market estimated at $500 billion to $740 billion over the next 10 years.  As new nations consider nuclear energy technology to produce low-carbon electricity, the United States should take a leadership role that will enhance the safety and nuclear nonproliferation regimes globally, while creating tens of thousands of new American jobs. The United States is the world leader in safe and efficient operation of nuclear power plants, with an average capacity factor of 90 percent or higher in each of the past 10 years.  When ranked by 36-month unit capability factor, the United States has the top three best performing nuclear reactors in the world, seven of the top 10, and 16 of the top 20.  nuclear energy facilities produce electricity in 31 states and have attained a four-fold improvement in safety during the past 20 years.  This underpinning in safety and reliability is one reason why America generates more electricity from nuclear energy than the next two largest nuclear programs combined.
  • Bilateral agreements on nuclear energy cooperation are vital to advancing global nonproliferation and safety goals as well as America’s interests in global nuclear energy trade.  A 123 agreement, named after section 123 of the Atomic Energy Act, establishes an accord for cooperation as a prerequisite for nuclear energy trade between the United States and other nations.  The agreement contains valuable nonproliferation controls and commitments.  One of the most significant elements of U.S. agreements is approval granted by our government as to how other countries process uranium fuel after it is used in a commercial reactor.  Under U.S. agreements, these nations cannot reprocess the fuel—chemically separating the uranium and plutonium—without U.S. notification and consent to do so.  This is a significant safeguard against the potential misuse of low-enriched uranium from the commercial sector.
  • Several public policy considerations must be weighed in evaluating the impact of 123 agreements, including those related to national security, economic development, energy production, and environmental protection. In the competitive global marketplace for commercial nuclear technology, inconsistent bilateral agreements will have unintended consequences for U.S. suppliers.  Imposing overly restrictive commercial restrictions or conditions in U.S. 123 agreements that are not matched by other nations’ bilateral agreements may significantly bias the country against selecting U.S.-based suppliers, even if the agreements don’t have malicious intentions.

  • The imposition of requirements that seem unnecessary and unfair can affect commercial decision-making by the affected country.  Such conditions put U.S. commercial contracts and jobs at risk. Moreover, if the country does not use U.S.-based technology, fuels or services, the value of conditions in the 123 agreement (i.e., consent rights) would be lost. Some U.S. leaders are proposing a prohibition on uranium enrichment and reprocessing as part of all bilateral nuclear energy agreements for cooperation.  Ensuring enrichment technology and reprocessing technology are used only for peaceful purposes is a paramount goal for government and industry. But U.S. 123 agreements are neither the best, nor in most cases, the appropriate mechanism to achieve that goal. 
  • Multilateral agreements are more appropriate mechanisms for policy regarding the global challenge of nuclear proliferation.  Promising mechanisms include the decision by the International Atomic Energy Agency to establish a uranium fuel bank, potential nuclear fuel lease/takeback contracts, and other multilateral, institutional nonproliferation arrangements.  In addition, the nuclear Suppliers Group (an international body of 46 nuclear technology supplier nations that sets standards for commercial nuclear trade) recently adopted new clear and strict criteria for the transfer of nuclear energy technology.  These institutional controls do not require the receiving country to cede sovereign rights, which the U.S. government and other countries with civilian nuclear energy programs would never give up. 
  • Fast-growing electricity needs in developing countries and concern about air quality and climate change are stimulating significant global demand for nuclear energy.  Sixty-six plants are being built worldwide and another 154 are in the licensing and advanced planning stage. U.S. suppliers are vying for business around the world – including China, Poland and India.  Continued U.S. leadership in global nuclear safety and nonproliferation matters go hand-in-hand with a strong presence in the global marketplace.  Both are critical to our national and global security.  We must continue to participate in worldwide trade and nonproliferation policy discussions, or cede leadership in these areas to other governments and industrial competitors.  Unless we choose engagement, America will lose tens of thousands of jobs and other benefits such trade has for our economy while forfeiting the nonproliferation benefits that 123 agreements are intended to achieve.

Royal Society calls for long-term nuclear plans [13Oct11] - 0 views

  • The government must establish long-term plans for a new generation of nuclear power plants so future generations are not left dealing with its legacy, experts urged on Thursday.Ministers must work with the industry to create a "holistic" strategy which deals effectively with reprocessing and disposal of spent nuclear fuel and does not treat it simply as "an afterthought", they warned.The new build programme must also take into account the UK's stockpile of civil plutonium - the largest in the world - created as a waste fuel from nuclear reactors but which can potentially be reprocessed into new nuclear fuel.
  • The warning comes as the government pushes ahead with a new generation of nuclear power stations in a bid to meet electricity demand and cut carbon emissions from the energy sector.In a report from the Royal Society, the group of experts said the handling of nuclear fuel throughout its working cycle must be considered to reduce security risks and the danger of proliferation of nuclear weapons.Research and development programmes are needed from the outset of the new build project to ensure fuel is managed properly, they added.Roger Cashmore, chairman of the Royal Society working group and head of the UK Atomic Energy Authority, said: "The last time any UK government articulated a coherent long-term plan for nuclear power was in 1955.
  • "We need to ensure that government and industry work together now to develop a long-term, holistic strategy for nuclear power in the UK."This must encompass the entire nuclear fuel cycle, from fresh fuel manufacture to disposal. Indeed, spent fuel can no longer be an afterthought and governments worldwide need to face up to this issue."He added: "While the government has made some positive moves towards an integrated approach to nuclear power, more must be done."The call comes after the energy secretary, Chris Huhne, signalled that a new generation of nuclear power plants would go ahead after a government-ordered review into the Fukushima disaster in Japan found no reason to curtail the use of reactors in the UK.

  • The review by chief nuclear inspector Mike Weightman examined the lessons that could be learned from the crisis at the Fukushima reactor when it was hit by a magnitude nine earthquake and subsequent tsunami in March.It revealed no "fundamental weaknesses" in the regulatory or safety assessment regimes of the UK nuclear industry, although it did outline 38 areas where improvements could be made.Prof Cashmore added: "Fukushima has shown that we cannot be complacent about the safety of nuclear power."However, the same principle must apply to nuclear security and non-proliferation. Both governments and the nuclear industry need to seriously reassess their responsibilities in these areas."

The Thorium Reactor, A Nuclear Energy Alternative [19Sep11] - 0 views

  • After Fukushima a great deal of awareness on the dangers of nuclear energy has ignited a series of reactions in society, mainly a generalized rejection to nuclear energy and a call to develop cleaner and safer sources of energy. When thinking about nuclear energy mainly 2 sources come to peoples minds, solar and wind power condemning any sort of nuclear power.  nuclear power has been associated with Weapons of Mass Destruction, radiation sickness and disease.  However, this is not due to the nuclear power itself but due to the nuclear fuel used to generate this nuclear power.
  • The above are just some of the most common byproducts, (better known as nuclear waste) of a nuclear fuel cycle, all of these substances are extremely poisonous, causing a variety of diseases, cancers and genetic mutations to the victim.  The worst part is that most of them remain in the environment of decades or even thousands of years, so if accidentally released to the environment they become a problem that future generations have to deal with.  Therefore, in nuclear energy the problem is in the fuel not in the engine. Lets start with the Thorium Reactors.  Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world.  It is estimated that every cubic meter of earth’s crust contains about 12 grams of this mineral, enough quantity to power 1 person’s electricity consumption for 12-25 years.  Energy is produced from thorium in a process known as the Thorium Fuel Cycle, were a nuclear fuel cycle is derived from the natural abundant isotope of thorium.
  • In today’s world the main fuel for nuclear power is a naturally occurring radioactive mineral, Uranium.  This mineral is one of the most dense metals in the periodic table which allows it to reach a chain reaction that can yield huge amounts of energy that can be exploited for an extended period of time.  Unfortunately the nuclear fuel cycle of Uranium produced extremely dangerous byproducts, commonly known as nuclear waste.  These are produced in liquid, solid and gaseous form in a wide variety of deadly substances, such as: Iodine 131 Strontium 90 Cesium 137 Euricium 155 Krypton 85 Cadmium 113 Tin 121 Samarium 151 Technetium-99

  • Thorium can be used as fuel in a nuclear reactor, and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.  These are some of the benefits of Thorium reactors compared to Uranium. Weapons-grade fissionable material is harder to retrieve safely and clandestinely from a thorium reactor; Thorium produces 10 to 10,000 times less long-lived radioactive waste; Thorium comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235; Thorium cannot sustain a nuclear chain reaction without priming,[22] so fission stops by default. The following conference by Kirk Sorensen explains a Liquid-Fuoride Thorium Reactor a next generation nuclear reactor.

Americans' Support for Nuclear Energy Holds at Majority Level 6 Months After Japan Accident [03Oct11] - 0 views

  • WASHINGTON, Oct. 3, 2011 -- /PRNewswire-USNewswire/ -- Six months after the Fukushima Daiichi accident in Japan, solid majorities of Americans still view nuclear energy favorably, still support the extension of operating licenses at existing facilities that meet federal safety standards, and still believe that construction of a new reactor is acceptable at the site of the nearest nuclear power plant that already is operating, a new national survey shows.While support for nuclear energy has declined from the historically high level seen one year ago, support on a variety of measures is holding at the majority levels found consistently in public opinion surveys conducted throughout the past decade.
  • In the new telephone survey of 1,000 U.S. adults, 62 percent of respondents said they favor the use of nuclear energy as one of the ways to provide electricity in the United States, with 35 percent opposed. Those strongly favoring nuclear energy outnumber those strongly opposed by a two-to-one ratio, 28 percent vs. 13 percent, according to the survey conducted Sept. 22-24 by Bisconti Research Inc. with GfK Roper. The survey was sponsored by the nuclear Energy Institute and has a margin of error of plus or minus three percentage points. Numerous surveys conducted by Bisconti Research over the past decade show that public support for nuclear energy topped 60 percent each year, rising as high as 74 percent of Americans in March 2010.
  • "While there is some evidence of impact of the Fukushima events, support for nuclear energy continues at much higher levels than in earlier decades," company President Ann Bisconti said. "Turmoil in oil-rich areas of the world and hikes in oil prices historically have focused public opinion even more on nuclear energy, and may have helped to preclude serious impact of events in Japan on public attitudes."Despite the Fukushima accident, 67 percent of Americans rate U.S. nuclear power plant safety high. This is identical to the safety rating found in a national survey last February, one month prior to the earthquake and tsunami that caused the Fukushima accident. Eighty-two percent of Americans believe that "we should learn the lessons from the Japanese accident and continue to develop advanced nuclear energy plants to meet America's growing electricity demand," the new survey showed.

  • Nuclear energy supplies electricity to 20 percent of U.S. homes and businesses, even though the 104 Nuclear facilities operating in 31 states constitute only 10 percent of the nation's electric generating capacity.Eighty-five percent of those surveyed agree that, "When their original operating licenses expire, we should renew the license of Nuclear power plants that continue to meet federal safety standards." Seven months ago, 88 percent of Americans agreed with this statement.
  • In the latest survey, 59 percent of Americans agree, "We should definitely build more nuclear power plants in the future." Thirty-eight percent disagree. Still, 75 percent of Americans agree that, "Electric utilities should prepare now so that new nuclear power plants could be built if needed in the next decade." Twenty-two percent disagree.Two-thirds of Americans (67 percent) say they would find a new reactor acceptable at the site of the nearest nuclear power plant that already is operating, while 28 percent find this unacceptable. Seven months ago, 76 percent of Americans found this expansion acceptable, with 20 percent saying it was not acceptable.
  • "This survey, like other recent surveys, confirms that large majorities of Americans associate nuclear energy with issues they care about, including clean air, reliable and affordable electricity, energy independence, and economic growth and job creation," Bisconti said.Details on the new survey are accessible at: http://www.nei.org/resourcesandstats/documentlibrary/reliableandaffordableenergy/reports/latest-trends-in-us-public-opinion-about-nuclear-energy-sept-2011.

The battle for the atom is heating up again [21Jun11] - 0 views

  • I have been rereading a 1982 book by Bertrand Goldschmidt titled “The Atomic Complex: A Worldwide Political History of Nuclear Energy.”
  • The two self-assigned homework projects are as part of a reflective effort to understand more about how human society moved from a period of optimism based on a vision of “Atoms for Peace” to a period where someone reading the advertiser supported press would believe that sensible people would logically consider giving up the whole technology out of fear of radiation and its health consequences.One of the hopeful lessons I have learned so far is that the initial conditions of our current fight to defend and expand the safe use of atomic energy are far different from those that faced the people engaged in the earliest battles against a well organized opposition to nuclear technology development. We have a much better chance of success now than we did then – and there are several reasons why that is true.
  • One condition that is vastly different is the ability of nuclear professionals to have their voices heard. No longer are most people who understand nuclear energy isolated in small communities with few media outlets. In the 1970s, a large fraction of nuclear professionals were located near remotely sited national laboratories or power stations. Today, though many still work at national labs or in small market communities like Lynchburg, VA, we are all globally connected to a vast network on the Internet. We have Skype, YouTube and blogs. Some of us know that major decision makers and journalists read or listen to our words on a regular basis. We are no longer shy about responding to misinformation and unwarranted criticism.
  • ...12 more annotations...
  • For example, many of you have probably seen or read the Associated Press hit piece on the effort by the Nuclear Regulatory Commission and the Nuclear industry to address the issue of aging Nuclear power stations
  • The encouraging thing about that response is that it happened on the SAME DAY as the AP report was released. After Dan published his report, he notified the world via Twitter that the post was up. I have already had the opportunity to retweet his announcement and to share his link in a conversation related to a Huffington Post article titled U.S. Nuclear Regulators Weaken Safety Rules, Fail To Enforce Them: AP Investigation and in a conversation on Joe Romm’s Climate Progress titled AP Bombshell: U.S. Nuclear Regulators “Repeatedly” Weaken Safety Rules or are “Simply Failing to Enforce Them”.Think about that – it has been just 24 hours since the AP story hit the wires, yet Nuclear professionals are already sharing a completely different side of the story without the filter of someone else deciding what is important.
  • However, the AP reporter, most likely someone who has never worked on an old car or repaired an old submarine, took a lot of stories out of context. He added a number of scary sounding inferences about the relationship between the regulators and the regulated. In response to the story, Dan Yurman, who blogs at Idaho Samizdat and was a professional journalist before he became a nuclear professional, reached out for real expertise.
  • He interviewed Dr. John Bickel, a man who has about 39 years worth of professional experience in plant aging, defense in depth and other safety related issues. You can read Dan’s excellent article at Associated Press Nukes the NRC on Reactor Safety.
  • It should be no secret to anyone that the average age of nuclear power plants in the US increases by almost exactly one year with every passing year. We are only officially building one plant right now, with four more that will enter that category as soon as the NRC issues the construction and operating licenses. It is also no secret that the NRC and the industry have been working hard to address aging as part of the effort to relicense plants for an additional 20 years, a process that is complete for more than 60 plants so far.
  • Another thing that is different about the fight over using atomic energy now, compared to the fight that happened in the late 1960s through the 1990s is that the opposition has a much less capable base of leaders. In the previous phase of the battle, the antinuclear movement grew out of a morally understandable effort to stop testing nuclear weapons in the earth’s atmosphere.
  • That effort was inspired by real world events like showering a Japanese fishing vessel with lethal doses of fallout from an ill-timed test in the middle of the Pacific ocean. It was led by some of the world’s most renowned atomic scientists, many of whom bore a deep moral guilt for their wartime efforts to build the Bomb in the first place.
  • When that effort succeeded in convincing the US, the UK and Russia to agree to stop atmospheric testing in 1963, some of the organizations that had been formed to do the heavy lifting saw substantial decreases in membership and contributions. After all, they could have easily hung up a large banner saying “Mission Accomplished” and closed up shop. Some did just that. Some persisted for a while with a variety of related issues like fighting against antiballistic missile installations and medium range rockets.
  • The groups organized against nuclear energy today are no longer led by world renowned scientists, though they do have some media celebrities with spotty professional histories and puffed up resumes. In many cases, they are grayer than I am and less well versed in the techniques of modern communications. Their fellow travelers on blogs and message boards routinely expose their own ignorance and sometimes their near illiteracy.
  • In contrast to the past, many of the renowned nuclear scientists and engineers in the profession today have no guilt at all. They did not participate in developing fearful weapons of mass destruction. Instead, they have spent their lives participating in an enterprise that provides massive quantities of emission free, low cost power to the people of the world. Seasoned professionals like Ted Rockwell, Margaret Harding, Meredith Angwin and Gail Marcus are out there blogging away and telling people what they know to be true about nuclear energy.
  • Enthusiastic younger people like Kirk Sorensen, Jack Gamble, and Suzy Hobbs are sharing optimistic visions for the future and explaining why they have chosen to support nuclear energy development, often in the face of numerous friends who disagree
  • I am encouraged. Atomic energy is alive and well; there is nothing that humans can do to eliminate its existence. We are entering a golden age of nuclear energy where facts and reality will overcome fictional tall tales spun by folks like Arnie Gundersen or Paul Blanche.

Why You Should Ignore Germany's Nuclear U-Turn [02Jun11] - 0 views

  • According to German Chancellor Angela Merkel, “We want the electricity of the future to be safe, reliable and economically viable.” And in her mind, nuclear power doesn’t fit the bill anymore. She’s wrong. The truth is, nuclear power is safe, reliable, clean and cheap. And that’s precisely why global nuclear capacity is going to keep increasing, by as much as 50% between now and 2020. It’s also the reason why the long-term investment thesis for uranium stocks remains compelling
  • Don’t Let Recent Events Mislead You As humans, we have a tendency toward recency bias. In other words, we give recent events extra importance when making decisions. The recent radiation crisis in Japan is an example.
  • believing that nuclear power is now suddenly unsafe is patently wrong. As the following chart shows, nuclear power is actually the safest form of energy production available. And if anything, the crisis at Japan’s 40-year-old Fukushima Daiichi plant is only going to increase the safety precautions at existing and new nuclear power plants
  • ...4 more annotations...
  • Not only is nuclear power safest, it also happens to be extremely clean. nuclear power generation produces virtually no greenhouse gases. It’s one of the most economical energy sources, too. It only costs about $0.04 per kilowatt hour (kWh) to produce electricity with nuclear power, compared to $0.08 per kWh for wind and more than $0.18 per kWh for solar.
  • While Germany Pulls a U-ey, Follow China, India and America Instead While Germany’s nuclear decision has made headlines this week, the positive future for nuclear power was underlined a few weeks ago when two of the fastest-growing global economies gave the industry a big shot in the arm. ~ China: On May 12, China’s nuclear Energy Association announced plans to boost the country’s nuclear power capacity as much as eight times by 2020. ~ India: A day later, India’s Atomic Energy Commission announced plans to increase production 13-fold by 2020. And they’re not alone. Although the United States didn’t announce any specific growth plans, it’s certainly not abandoning nuclear power production.
  • In the aftermath of the Japan crisis, the U.S. Nuclear Regulatory Commission said it would scrutinize Nuclear license renewals. But in April, the commission renewed the operating license for the largest Nuclear power plant in the United States for another 20 years. And as Jeff Eerkens, an adjunct professor at the University of Missouri’s Nuclear Science and Energy Institute, estimates, the United States needs to quintuple its number of power plants to keep up with electricity demand.

The Hindu :AEC chief puts odds of N-plant accidents at '1-in-infinity' [10Nov11] - 0 views

  • The probability of an accident due to a nuclear plant is one is to infinity and all atomic power plants in the country conform to safety standards, chairman of Atomic Energy Commission Srikumar Banerjee said on Thursday. “At least 1.75 lakh people die due to road accidents in a single year whereas there are nearly 14,000 nuclear plants in the world and the casualty rate till date is just 52,” Dr. Banerjee told reporters on the sidelines of the golden jubilee celebrations of Terminal Ballistic Research Laboratory (TBRL) at Ramgarh, near Chandigarh. Pointing out that no human activity can be risk-free, he said there was a definite need for creating awareness and programmes should to be intensified to convince the people in the neighbourhood of a proposed or existing nuclear plant. He said human body faces more radiation during a CT scan than working in a nuclear power plant.
  • Referring to the recent Fukushima nuclear accident, Dr. Banerjee said it happened after a gap of 25 years and the cause and effect of the accident was earthquake followed by a tsunami. “It was not a nuclear accident... immediately after the earthquake, the nuclear reactor shut down and nuclear chain reaction stopped,” he said adding it was a complete station blackout as the decay heat produced in the plant could not be taken out. He, however, said the total casualty due to the nuclear accident was zero. “The spread of radiation was not as high as it was projected,” he said talking about the nuclear accident in Japan. After a nuclear reactor is shut down the energy level comes down to around 2 per cent from 100 per cent due to heat decay, Dr. Banerjee said. He, however, exuded confidence all nuclear plants in the country are safe and conform to the standards of Atomic Energy Regulatory Board and are taken care of by nuclear Power Corporation. “India too experienced earthquakes and tsunami in the past but there was no nuclear accident as the nuclear plants had all the gadgets to give signal much in advance,” he said. Dr. Banerjee rejected that alarm bells had rung in India after the Japanese nuclear accident. “All steps needed for safety and security for nuclear plants have been taken by nuclear Power Corporation,” he added.
  • He, however, stressed that it was necessary to strengthen the mechanism in the passive cooling system in nuclear plants in India. In the passive cooling system, heat can be taken out from the plant. Responding to a query regarding protests by habitants before setting up a nuclear plant in their neighbourhood, he said what is needed is to explain things to local people in simple local language and also convince them what actually the plant is. After land acquisition, a package must be given to the affected people and at all costs excellent relationship is needed with people living around the plant. He termed it as “baseless,” the allegation that nuclear radiation comes out from the nuclear plant. Besides, the plants along the coastal areas do not have any effect on the lives of fish, he added.

IEA - OECD: Nearly 25 Percent Of Global Electricity Could Be Generated From Nuclear Power By 2050 [21Jun11] - 0 views

  • The latest reactor designs, now under construction around the world, build on over 50 years of technology development. The roadmap notes that these designs will need to be fully established as reliable and competitive electricity generators over the next few years if they are to become the mainstays of nuclear expansion after 2020
  • Almost one quarter of global electricity could be generated from nuclear power by 2050, making a major contribution to cutting greenhouse gas emissions. This is the central finding of the nuclear Energy Technology Roadmap, published by the International Energy Agency (IEA) and the OECD nuclear Energy Agency (NEA). Such an expansion will require nuclear generating capacity to more than triple over the next 40 years, a target the roadmap describes as ambitious but achievable.
  • Speaking from the East Asia Climate Forum in Seoul, IEA Executive Director Nobuo Tanaka said: “Nuclear energy is one of the key low-carbon energy technologies that can contribute, alongside energy efficiency, renewable energies and carbon capture and storage, to the decarbonisation of electricity supply by 2050.” NEA Director General Luis Echávarri stated: “Nuclear is already one of the main sources of low-carbon energy today. If we can address the challenges to its further expansion, Nuclear has the potential to play a larger role in cutting CO2 emissions.”

  • Financing the construction of new nuclear plants is expected to be a major challenge in many countries
  • No major technological breakthroughs will be needed to achieve the level of nuclear expansion envisaged, the roadmap finds. However, important policy-related, industrial, financial and public acceptance barriers to the rapid growth of nuclear power remain. The roadmap sets out an action plan with steps that will need to be taken by governments, industry and others to overcome these. A clear and stable policy commitment to nuclear energy as part of overall energy strategy is a pre requisite, as is gaining greater public acceptance for nuclear programmes. Progress in implementing plans for the disposal of high-level radioactive waste will also be vital. The international system of safeguards to prevent proliferation of nuclear technology and materials must be maintained and strengthened where necessary.
  • The latest reactor designs, now under construction around the world, build on over 50 years of technology development. The roadmap notes that these designs will need to be fully established as reliable and competitive electricity generators over the next few years if they are to become the mainstays of nuclear expansion after 2020.
  • For the longer term, the continued development of reactor and fuel cycle technologies will be important for maintaining the competitiveness of nuclear energy
  • The Nuclear Energy Technology Roadmap is the result of joint work by the IEA and the OECD Nuclear Energy Agency (NEA) and is one of a series being prepared by the IEA in co operation with other organisations and industry, at the request of the G8 summit at Aomori (Japan) in June 2008. The overall aim is to advance development and uptake of key low-carbon technologies needed to reach the goal of a 50% reduction in CO2 emissions by 2050.
  • Nuclear generating capacity worldwide is presently 370 gigawatts electrical (GWe), providing 14% of global electricity. In the IEA scenario for a 50% cut in energy-related CO2 emissions by 2050 (known as the “BLUE Map” scenario), on which the roadmap analysis is based, Nuclear capacity grows to 1 200 GWe by 2050, providing 24% of global electricity at that time. Total electricity production in the scenario more than doubles, from just under 20 000 TWh in 2007 to around 41 000 TWh in 2050.

Senator Lamar Alexander: "Nuclear Power Is the Most Reliable and Useful Source of Green Electricity Today" [16JUN10] - 0 views

  • U.S. Senator Lamar Alexander (R-Tenn.), chairman of the Senate Republican Conference, delivered a speech this week at the International V.M. Goldschmidt Conference in Knoxville.  Alexander serves on the Senate Environment and Public Works Committee and is the chairman of the Tennessee Valley Authority Congressional Caucus.  His remarks as prepared follow:
  • When
  • in a speech in Oak Ridge in May of 2009, I called for America to build 100 new nuclear plants during the next twenty years.  nuclear power produces 70 percent of our pollution-free, carbon-free electricity today.  It is the most useful and reliable source of green electricity today because of its tremendous energy density and the small amount of waste that it produces.  And because we are harnessing the heat and energy of the earth itself through the power of the atom, nuclear power is also natural.
  • ...10 more annotations...
  • Forty years ago, nuclear energy was actually regarded as something of a savior for our environmental dilemmas because it didn’t pollute.  And this was well before we were even thinking about global warming or climate change.  It also didn’t take up a great deal of space.  You didn’t have to drown all of Glen Canyon to produce 1,000 megawatts of electricity.  Four reactors would equal a row of wind turbines, each one three times as tall as Neyland Stadium skyboxes, strung along the entire length of the 2,178-mile Appalachian Trail.   One reactor would produce the same amount of electricity that can be produced by continuously foresting an area one-and-a-half times the size of the Great Smoky Mountains National Park in order to create biomass.  Producing electricity with a relatively small number of new reactors, many at the same sites where reactors are already located, would avoid the need to build thousands and thousands of miles of new transmission lines through scenic areas and suburban backyards. 
  • While nuclear lost its green credentials with environmentalists somewhere along the way, some are re-thinking nuclear energy because of our new environmental paradigm – global climate change.  nuclear power produces 70 percent of our carbon-free electricity today.  President Obama has endorsed it, proposing an expansion of the loan guarantee program from $18 billion to $54 billion and making the first award to the Vogtle Plant in Georgia.  Nobel Prize-winning Secretary of Energy Steven Chu wrote recently in The Wall Street Journal about developing a generation of mini-reactors that I believe we can use to repower coal boilers, or more locally, to power the Department of Energy’s site over in Oak Ridge.  The president, his secretary of energy, and many environmentalists may be embracing nuclear because of the potential climate change benefits, but they are now also remembering the other positive benefits of nuclear power that made it an environmental savior some 40 years ago
  • The Nature Conservancy took note of nuclear power’s tremendous energy density last August when it put out a paper on “Energy Sprawl.”  The authors compared the amount of space you need to produce energy from different technologies – something no one had ever done before – and what they came up with was remarkable.  nuclear turns out to be the gold standard.  You can produce a million megawatts of electricity a year from a nuclear reactor sitting on one square mile.  That’s enough electricity to power 90,000 homes.  They even included uranium mining and the 230 square miles surrounding Yucca Mountain in this calculation and it still comes to only one square mile per million megawatt hours
  • And for all that, each turbine has the capacity to produce about one-and-a-half megawatts.  You need three thousand of these 50-story structures to equal the output of one nuclear reactor
  • When people say “we want to get our energy from wind,” they tend to think of a nice windmill or two on the horizon, waving gently – maybe I’ll put one in my back yard.   They don’t realize those nice, friendly windmills are now 50 stories high and have blades the length of football fields.  We see awful pictures today of birds killed by the Gulf oil spill.  But one wind farm in California killed 79 golden eagles in one year. The American Bird Conservancy says existing turbines can kill up to 275,000 birds a year.
  • Coal-fired electricity needs four square miles, because you have to consider all the land required for mining and extraction.  Solar thermal, where they use the big mirrors to heat a fluid, takes six square miles.  Natural gas takes eight square miles and petroleum takes 18 square miles – once again, including all the land needed for drilling and refining and storing and sending it through pipelines.  Solar photovoltaic cells that turn sunlight directly into electricity take 15 square miles and wind is even more dilute, taking 30 square miles to produce that same amount of electricity.
  • , wind power can be counted on to be there 10 to 15 percent of the time when you need it.  TVA can count on nuclear power 91 percent of the time, coal, 60 percent of the time and natural gas about 50 percent of the time.  This is why I believe it is a taxpayer rip-off for wind power to be subsidized per unit of electricity at a rate of 25 times the subsidy for all other forms of electricity combined. 
  • the “problem of nuclear waste” has been overstated because people just don’t understand the scale or the risk.  All the high-level nuclear waste that has ever been produced in this country would fit on a football field to a height of ten feet.  That’s everything.  Compare that to the billion gallons of coal ash that slid out of the coal ash impoundment at the Kingston plant and into the Emory River a year and a half ago, just west of here.  Or try the industrial wastes that would be produced if we try to build thousands of square miles of solar collectors or 50-story windmills.  All technologies produce some kind of waste.  What’s unique about nuclear power is that there’s so little of it.
  • Now this waste is highly radioactive, there’s no doubt about that.  But once again, we have to keep things in perspective.  It’s perfectly acceptable to isolate radioactive waste through storage.  Three feet of water blocks all radiation.  So does a couple of inches of lead and stainless steel or a foot of concrete.  That’s why we use dry cask storage, where you can load five years’ worth of fuel rods into a single container and store them right on site.  The Nuclear Regulatory Commission and Energy Secretary Steven Chu both say we can store spent fuel on site for 60 or 80 years before we have to worry about a permanent repository like Yucca Mountain
  • then there’s reprocessing.  Remember, we’re now the only major nuclear power nation in the world that is not reprocessing its fuel.  While we gave up reprocessing in the 1970s, the French have all their high-level waste from 30 years of producing 80 percent of their electricity stored beneath the floor of one room at their recycling center in La Hague.  That’s right; it all fits into one room.  And we don’t have to copy the French.  Just a few miles away at the Oak Ridge National Laboratory they’re working to develop advanced reprocessing technologies that go well beyond what the French are doing, to produce a waste that’s both smaller in volume and with a shorter radioactive life.  Regardless of what technology we ultimately choose, the amount of material will be astonishingly small.  And it’s because of the amazing density of nuclear technology – something we can’t even approach with any other form of energy

TOWARD REAL ENVIRONMENTAL SUSTAINABILITY BY MOLECULAR NANOTECHNOLOGY - 0 views

    2.2.5. Nuclear Wastes MNT cannot treat Nuclear wastes and render them harmless directly, for MNT only work with atoms and molecules, not nuclei.  Yet indirectly, by lowering the cost of energy and equipment, MNT can offer us the means for a clean, permanent solution to the untreatable Nuclear wastes left over from the Nuclear era. Nuclear wastes can be collected, concentrated by specific nanobots. Products of MNT could help with conventional approaches to dealing with Nuclear waste, helping to store it in the most stable, reliable forms possible.  Using nanomachines, we could seal them in self-sealing containers and powered by cheap nano-solar energy (10).  These would be more secure than any passive rock or cask.  When MNT has developed cheap, reliable spacecraft, the concentrated Nuclear wastes can be transported to the moon and bury them in moon's dead, dry rock by nanobots, or to other planets that still radioactive, or even shoot them directly into the sun. Underground nano-atom smasher powered by cheap solar cells can also be devised to treat Nuclear wastes. This is a reverse process of Nuclear engineering.  Instead of smashing nonradioactive target and harvesting for radioactive substance, the nanomachine will smash radioactive target and harvest for nonradioactive substance.  The smashing and harvesting process will continue stability is achieved.  Fig. 9 illustrates a few routes for resolving Nuclear waste piles that accumulated in the environment and TDBT is at loss on dealing with them.

Oak Ridge National Laboratory: Advancing The Nuclear Enterprise Through Better Computing [24May10] - 0 views

  • In the area of nuclear energy, the nuclear Modeling staff specializes in developing and applying computational methods and software for simulating radiation in order to support the design and safety of nuclear facilities, improve reactor core designs and nuclear fuel performance, and ensure the safety of nuclear materials, such as spent nuclear fuel. The nuclear Modeling staff is internationally known for developing and maintaining SCALE, a comprehensive nuclear analysis software package originally developed for the nuclear Regulatory Commission with signature capabilities in the criticality safety, reactor physics and radiation shielding areas. In recent years, ORNL has placed an emphasis on transforming its current capabilities through high-performance computing, as well as the development of new and novel computational methods
  • Scientists at the Nuclear Science and Technology Division of the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) are merging decades of Nuclear energy and safety expertise with high-performance computing to effectively address a range of Nuclear energy- and security-related challenges.
  • John Wagner, Technical Integration Manager for Nuclear Modeling within ORNL's Nuclear Science and Technology Division (NSTD), says one of the goals of his organization is to integrate existing Nuclear energy and Nuclear national security modeling and simulation capabilities and associated expertise with high-performance computing to solve problems that were previously unthinkable or impractical in terms of the computing power required to address them.

  • "Traditionally, reactor models for radiation dose assessments have considered just the reactor core, or a small part of the core," Wagner says. "However, we're now simulating entire nuclear facilities, such as a nuclear power reactor facility with its auxiliary buildings and the ITER fusion reactor, with much greater accuracy than any other organization that we're aware of." More accurate models enable nuclear plants to be designed with more accurate safety margins and shielding requirements, which helps to improve safety and reduce costs. The technology that makes this sort of leading-edge simulation possible is a combination of ORNL's Jaguar, the world's fastest supercomputer; advanced transport methods; and a next-generation software package called Denovo

An Inside Look At The Current State Of The Nuclear Industry [29Sep11] - 0 views

  • As I’ve mentioned before, I’m a fan of nuclear energy.  I was able to get an inside look at the current state of the nuclear industry from a friend at Qualitech Solutions named Chris Sewell.  Qualitech Solutions provides mission-critical software to many industries, including the energy industry.  They have customers that are involved in nuclear utilities as well as design engineering firms working on major construction projects.  Qualitech Solutions has been in business for more than a decade.
  • Sewell says, “There is a hesitancy to continue with nuclear construction projects amidst the public concern over nuclear safety.  Society as a whole has become hypersensitive with anything pertaining to nuclear plant issues and safety.  The Fukushima incident not only altered the social climate, but also affected the financial backing of various new construction projects. There is however, a general consensus that due to its low carbon imprint, nuclear energy must be part of our energy future.”
  • The general public fears nuclear energy.  That is understandable considering the information that the public has been given.  The catastrophes and the mistakes are front page news.  But if the general public had more information about how the best nuclear plants are run, the opinion could turn.  This is why I asked Sewell about the success of nuclear energy in France.

  • The French generate approximately 80% of their energy using nuclear power.  They have realized the long-term financial and environmental benefits to nuclear power and have continued supporting the industry and its growth within their country and abroad.  AREVA, the French nuclear engineering firm, continues to work with partner companies to license and construct new nuclear plants and fuel facilities, such as the uranium enrichment plant in Idaho.” But in other countries, “nuclear plants are trying to get by with fewer people,” Sewell explained.  However, the more safety mechanisms that are developed in the industry, the more financial support the nuclear energy industry will receive.  One big safety development is in regard to the nuclear reactors themselves.
  • The newest nuclear reactors (Generation IIIs) have additional layers of safety and technology to stave off a meltdown in the event of a power loss (as happened at Fukushima).  The first of the Generation III reactors is due to come online in 2016 at The Vogtle Electric Generating Plant, located in Georgia,” said Sewell. The more safety measures that are developed, the more proactive the nuclear energy industry can be in addressing problem areas before a catastrophe happens.  I'm sure this won't make everyone feel safe tonight though, will it?

What to hate about nuclear energy [14Sep11] - 0 views

shared by D'coda Dcoda on 14 Sep 11 - No Cached
  • Reconsidering my support for nuclear energy I have found that it is only based in a desire to use it as a tool in the rather important fight against global warming and global meltdown. That in turn makes it possible to say “I hate nuclear energy. I just hate global warming more. So I support using it exactly until that problem is solved.” I said as much in my post yesterday with the nice title “Shut down those filthy nuclear reactors”.
  • So, what is there to hate about nuclear energy? Imagine you are a supporter of nuclear energy that is pushed by a silly reason like anger over being insulted by some random stranger on the Internet to actively look for anything that might be a problem with your former position. That is exactly what I have done. As a result, I have found basically two problems with it. One, which is the more important point, is the fact that the pro-nuclear position has lost in Germany, the only country where I actually have a vote. There is no German party I could vote for that supports building new nuclear reactors.
  • The victory of German anti-nuclear forces was quite decisive. That means as far as Germany is concerned, nuclear is just not a realistic option any more. Pro-nuclear advocacy is a waste of time, and a fringe minority position. Japan, the other country I might have some influence, is not quite as hopeless. Still advocating for a large increase in nuclear energy there does not seem a promising strategy.

  • The other thing I hate about nuclear energy is that most of pro-nuclear advocates are against renewable energy. That is not compatible with my point of view, making this a very efficient wedge issue for the anti-nuclear forces to exploit. Since most of the pro-nuclear advocates insist on bashing renewable energy, that point puts me out of the pro-nuclear advocacy business. For example, I regard the “Atomic Insights” blog by Rod Adams as hostile territory right now, and I am done writing any comments there for the time being.
  • So where does that leave me? I don’t exactly know yet. There are a couple of things that are clear already, however. One is that if anybody asks me to choose between nuclear and renewable, I will always choose the latter. That makes any form of pro-nuclear advocacy based on bashing renewable energy quite unacceptable to me. The other is that I am not quite joining the anti-nuclear advocates yet. I still think nuclear is needed as the most effective tool in the box against global warming. But my enthusiasm for advocating for that particular solution went down a couple of notches, so I will probably just focus more on discussing renewable energy issues.
